Answer 16

@jdoe0001 is "Approximately, 63.02 *10^6 more kilograms is the mass of an aircraft carrier than the mass of a freight train" the answer?

Answer 17

yes
that's correct BUT
scientific notation, uses only one number to the left of the dot
you have two numbers \(\bf \underline{63}.02\times 10^6\)

Answer 18

so is it 6.3?

Answer 19

\(\bf 6.302\times 10^7\) yeap

Answer 20

same thing, we simply move the dot over to the left one more slot
so we end up with only one digit on the left side :)
